No negative rates for the putative Bancor... Keynes must surely be rotating in his grave. It turns out the IMF is not going to lend SDRs for less than nothing, thus breaking ranks with some well-known central banks out there (no need to name names), and even the central bank-manipulated "market" in which investors accept negative rates on certain government bonds as if that made any sense.

Instead, the IMF has decided to set a floor for its SDR interest rate to maintain its role as a profit center…it will be at what is nowadays a downright usurious height of 0.05%. So at least at the IMF, there will be no pretense that time preferences can actually turn negative.
